The Siemens 3RT2016-2BB41 is a three-pole Sirius power contactor designed for AC-3e/AC-3 motor control tasks. With a 24 V DC coil, it energizes to switch a rated load of up to 9 A and up to 4 kW at 400 V, and it includes an auxiliary contact: 1 NO, along with a spring-loaded terminal for reliable wiring, all in the compact S00 size. This model is part of the Sirius 3RT family of three-pole contactors, which covers devices rated up to 250 kW. The three-pole configuration ensures balanced switching across all phases, making it suitable for panel-mounted motor starters in control cabinets. The 3RT2016-2BB41's coil voltage of 24 V DC allows straightforward integration with low-voltage control logic, while the spring-loaded terminals and single NO auxiliary contact support expanded control options in standard industrial circuits.
